PAUL B. KLUGH, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CABLE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

MUSIC-SHEET-CONTROLLING DEVICE.

Application filed November 22, 1911.

To all whom it may concern:

Be it known that 1, PAUL B. KLUcI-I, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Music-Sheet-Controlling Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to instruments employing a traveling controlling sheet in connection with a tracker or equivalent means for transmitting impulses from the sheet and has as its particular object the provision of means for automatically correcting any deviation of the sheet from its normal path. A further object of my invention resides in the particular arrangement and combination of parts hereinafter described.

Referring to the accompanying drawings, Figures 1 and 1" are complemental views showing my invention as applied to an automatic player mechanism for a musical instrument;

Fig. 2 is a diagrammatic view showing the electric circuits employed;

Fig. 3 is a detail view taken on line 3-3 of Fig. 1, and illustrating one of the sets of electromagnets Fig. 1 is a perspective view showing that part of my invention which cooperates directly with the controlling sheet.

Figs. 5 and 6 refer to a modified form of my invention.

Throughout the various views the same elements are referred to by the same reference numerals.

Referring more particularly to the drawings, 1 is the usual take-up roll, and 2 the music roll of an automatic player mechanism for a musical instrument. These rolls are driven by any preferredform of pneumatic motor such as 3, through intermediate gearing 3 such as is well known in the art. The roll 1 is carried on shaft 1 while roll 2 is supported in the usual manner by shaft 5 and socket 5, which extend through openings in the tracker box 6. Outside of each end of the box 6 is a part of the movable frame 7 in which the shafts 4E and 5 are rotatably mounted. Rods 8S pass through from one part of the frame 7 to the other, connecting the two parts rigidly together.

Specification of Letters Patent.

Patented Sept. 11, 191 7.

Serial No. 661,846.

Carried on the right hand part of the frame 7 is the gear mechanism 3 for driving the rolls. At the left hand end of one of rods 8 is carried a bracket 9 which supports the left end of the music roll socket 5. The movable frame 7 is attached to a pair of pneumatics 10-10 by means of a connecting link 11. The pneumatics 10-10 are provided with two movable plates 12 mounted on a central fixed plate 13, the movable plates 12 being connected by a link 141-. The fixed plate 13 is braced to the box 6 by a piece 15. It will now be apparent that if the movable plates 1212 are operated to the right that the frame 7 will be correspondingly actuated and the music rolls pushed farther t0 the right by means of the collars 16 carried on the ends of the shaft, whereas if the movable plates 1212 are shifted to the left the motion of the plates will be transmitted in the same manner, thus moving the rolls 1 and 2 to the left.

The mechanism by which the pneumatics 10 are thus controlled will now be described. To the right of the motor 3 is shown a pneumatic 24. hen the vacuum is thrown on the apparatus for playing, the pneumatic 24 is collapsed whereby the end of the arm 25 is caused to come into contact with the spring switch 26, thus forcing it against the contact 27 closing an electric circuit.

At the same time that the arm 25 thus closes the circuit through contacts 26 and 27 it also operates a rod 28 to throw in the clutch which controls the movement of the take-up roll.

Referring more particularly to Figs. 2 and 3, we see that when the circuit is closed at points 26 and 27 the circuit of the battery 29 may pass through the wires 30 and 31 through one or the other of the electromagnets 32, 33 to the contact point 3 1 or 35. Pivotally mounted so as to swing between the contacts 34: and 35 is a switch arm 36. lVhenever arm 36 is in contact with one of its cooperating contact points the battery circuit is then closed through the wire 37. Now it will be understood that the arm 36 is controlled by the position of the music sheet and whenever arm 36 makes contact with one of the points 3 1, 35 the corresponding magnet 32, 33 will be actuated to attract its cooperating armature 38, 39. Now these armatures act as valves covering the inlets to tubes f0 and 41 which lead into the interior of the pneumatic 10. WVhen one of the armatures is lifted from its seat atmospheric air is allowed to enter the corresponding pneumatic 10, thus inflating the pneumatic and operating the rod 11 to change the position of the frame 7 and consequently the position of the music rolls in the manner previously described.

It will be noted by reference to Figs. 1 and 3 that the magnets 32, 33 are mounted upon the movable plates 12, although in the diagrammatic view in Fig. 2 it would appear that they were separately mounted.

The manner in which the arm 30 cooperates with the music sheet is best illustrated in Fig. l where it will be seen that the arm 30 is one end of a rod 42 which is journaled on a pivoted bracket 43. At the end of the rod 42 opposite from the arm 36 is an arm 44 which contacts with the edge of the music sheet by means of a flattened face as shown.

In setting up my device it is adjusted so that the apertures in the music sheet register with the corresponding apertures in the tracker boardas required for perfect operation. The arm 41 is then adjusted for light cont-act with the edge of the sheet while at the same time the arm 36 stands midway between the points 34; and The contact between the sheet and the arm 41 can be adjusted as desired by swinging bracket 13 around its pivot point such as 49 by means of some convenient device as for instance the thumb piece 18. Now if the music sheet tends to shift to the right or to the left the arm 36 will make cont-act with the corresponding point so as to close the circuit of one of the eleetromagnets 32. 33 and return the music sheet to its normal position in the manner previously described. It will be seen that the arm 44: is positively moved in one direction by the action of the music sheet, while it is caused to move in the opposite direction to follow the sheet by the weight of the horizontal portion 30.

It will be seen also by reference to Figs. 1, 1 and 2, that the branch circuits in which the elec'troinagnets 32, 33 are placed also contain electric lamps 45%;). lVhen the circuits of one of the electro-magnets is closed its corresponding lamp will be lighted, thus giving an indication of the relative position of the perforated sheet 46 with respectto the tracker board 47. Thus the operator is notified whether the sheet tends to run in its correct position or not, and if it tends to run to one side of its proper position the bracket 43 may be adjusted so as to change the relative position of the sheet at which the shifting mechanism is brought into play.

Referring more particularly to Figs. and 0, Fig. 5 is a front elevation of the modified form of my invention while Fig. 6 is a cross sectional View taken on line 6-6 of Fig. 5. In the form of my device shown in Figs. 5 and (3, the electrical features are the same as in the form first described, but the mechanical arrangement is somewhat different. As shown in Fig. 5, rods SS are extended to the left so that the brackets 107107 support the central board 13 of the pneumatics 1010. so that the pneumatics move with the shiftable rods 8. Moreover, the brackets at each end of the movable frame are extended up to form bearings 100 for a rod or shaft 1.01. The rod 101 is bent at one end to form a lever arm which engages with a slotted member 102 which is shown in both Figs. 5 and 6, being dotted in Fig. 6. Carried on the end of rod 101 opposite the pneumatics 10 is a lever arm 103 which carries a cam 101. If now the pneumatics 10 are actuated, the rod 101 is rotated to move the inclined inner face of the cam 104 over the end of the music roll shaft 5, thus moving the music roll longitudinally with respect to the rods 8. The rods 8 are made adjustable with respect to the box 0 by means of a nut 105, which is placed in a recess in the lower member of the box and engages with a screw threaded portion 100 on the lower one of the rods 8. This arrangement of a nut working on a threaded portion of one of the rods 8 may obviously be employed in Figs. 1 and 1 if desired. By this means the entire gearing for the music and take-up rolls, as well as the shifting pneumatics .is set so that the perforations in the music sheet register with the openings in the tracker board and any lack of adjustment due to warping of the music sheet is taken care of by shifting the music roll relatively to the rods 88.

In Figs. 1 and 1 the pivoted bracket 3 is suspended from the tracker box 6, unless equipped with adjusting means such as not 105, but in the form shown in Fig. 5 this bracket with its accompanying contacts, and swinging contact member is necessarily mounted on a part of the shiftable frame, preferably the central rod 8, so that the bracket may move with the frame when shifted as by the nut 105.

It will be understood by those skilled in the art that while the arrangement shown and described is the preferred form of my invention, that my invention may be applied in various ways. For instance it will be seen that while I have shown two pneumatics for shifting the position of the music rolls that one only might be employed and a guide provided on one edge of the sheet so that it would be prevented from wandering from its correct position upon the side of the guide. Furthermore while I have shown and described a. pneumatic as being the immediate means for shifting the position of the music rolls it is apparent that the pneumatics are not essential but that the movement might be furnished by solenoids directly instead of by electromagnets controlling the operation of Pneumatics. Moreover it will be apparent that only one solenoid might be so used, the function of the other solenoid being taken by a guide as mentioned in connection with the pneumatics.

Accordingly it will be understood that I do not mean to be limited in the application of my invention to the exact arrangement shown but that I contemplate all modifications and rearrangements of the herein described invention which are embraced within the scope of the appended claims.
